\section1 Attached property must be attached to an object deriving from a particular type
 
\section2 What happened?
You instantiated an attached property in an object of the wrong type.
 
\section2 Why is this bad?
The attached property will not work.
 
\section2 Example
\qml
import QtQuick
 
Item {
    QtObject {
        LayoutMirroring.enabled: true
    }
}
 
\endqml
To fix this warning, change the enclosing type to inherit from the type
mentioned in the warning message:
 
\qml
import QtQuick
 
Item {
    Item {
        LayoutMirroring.enabled: true
    }
}
 
\endqml
